Fines (grains less than 140 mesh) should be held to less than 1%. Agglomerated or compound grains (found on the 40 mesh or above screen) should be less than 3%. Loss of Ignition (LOI): To determine loss of ignition, a small sample of sand (generally weighing 5-10g), is heated to between 870°C and 980°C for one hour.
